my current solution is adding a small random value to the x, y data point, but it is not very flexible since I don't the scale of the original value (thus don't know how small is small).

any code available?

thanks!

yes, I have done. Thanks a lot for the help!

yes! the ContourPlot may be just what I wanted, i'll look at it now and provide feedback

thanks!

i have tried bubblechart.
the thing is that some of the bubble is so big and overlap others.

I'll try other suggestions .

Thanks!

Can I use wafermap?

wow, that's fast and is a huge help .
I'll check it now.

thanks a lot!

Hi,
I have a dataset like this (x, y, value).
Can I use JFreechart to plot it?

For instance, in a XYScatterPlot,
draw the size or color of the node relative to the "value"?

Or any other type of chart?

Thanks for your attention.

I think you can process the data first (making num/total) before sending it to the plot.
